Application September 28, 1945, Serial No. 619,086

2 Claims.` (Cl. 12S-185) This invention relates to medicament applicators of the inhaler type :and has reference in pare ticular to one in which a hand pressure bulb is embodied and conveniently utilized to assist the user in attaining more effective and beneficial and all around results.

An object of the invention is to generally and otherwise improve upon inhalers in this line of endeavor, this with a View toward affording manufacturers and users an improved type of accessory which, it `is believed, is more aptly fitted for the purposes intended and otherwise susceptible of attaining desired ends.

In carrying out the principles of the invention, I utilize two forms of the invention, these having certain common characteristics in that each is characterized by a case having a nostril insertion nozzle at one end, and a hand actuated pressure bulb at the opposite end, there being a container in the case which is adapted to contain raw cotton or similar absorbent, the latter to be saturated with a medicament and said medicament being discharged through the nozzle for use.

Other features, advantages and objects of the invention Will become more readily apparentfrom the following description and the accompanying illustrative drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

Figure l is a central longitudinal view through a pressure inhaler constructed in accordance with the principles of the invention.

Figure 2 is a similar View showing a modified type of inhaler.

Figure 3 is a horizontal section, this on the plane of the lines 3 3 of Figure 2, looking in the direction of the arrows.

Reference is first had to Figure 1 from which it will be seen that the case, which is of appropriate dimensions and material is denoted by the numeral 5. This is preferably frusto-conical and is provided at its lower end With a nipple 6 one portion projecting into the lower part of the case, and the other portion projecting outwardly and beyond the case, the latter having a squeeze-bulb l mounted thereon. The bulb is provided with the usual air inlet element 8. The neck of the bulb is iitted on the nipple 6 to force air into the interior of the case. The case is lined with an appropriate filler 9 which is simply bored to accommodate the cylinder I0, said cylinder being open at its opposite ends and charged with raw cotton or the like II. There is an air chamber at I2 into which the air from the bulb is discharged for passage through the raw cotton. The upper end of the case is internally screw-threaded to accommodate a closing disc I3, said closing disc having a central tapered nozzle I4 for insertion in the nose oi the user. A suitable dome-type cap I5 is provided, this covering the nozzle and being threaded on the case as at I6 for ready application and removal.

In using this form of the invention, the medicament is dropped into a container lil by way of the nozzle M, the cap I5 having rst been removed. The medicament thus loads the absorbent cotton I I. Hence, by pressing the bulb 'I the incoming air under pressure forces the medicated fumes out through the nozzle I4, achieving the desired ends in an obvious and suitable manner.

Referring now to the modified form of the invention seen in Figure 2, I also provide a frustoconical case I'I with a nipple i8 uniting the bulb i9, thebulb having an air inlet 20. The air is thus forced into the chamber 2l, this chamber being defined in the present instance by a partition 22 in the case. The partition is provided with circumferentially spaced air tubes 23 permitting the air to pass from the Chamber `2| into the chamber 24. In the latter chamber I provide a cylinder 25 which is charged with raw cotton or the like 26. A small tube 21 is iitted down into the cylinder and submerged in the raw cotton and terminates in spaced relation to the partition 22. The numeral 28 designates a suitable bracing element securing the upper end of the tube 2l in proper relationship to the tapered nozzle '29 on the disc 30 threaded into the case. The case is also externally screw threaded to accommodate the dome-like cap 3|. It will be noted that the discharge end of the vapor and fume delivery tube 21 terminate inwardly of the discharge end or' the nozzle 29.

y In viewing the forms of the invention shown it is to be repeated that medicine is dropped in the nozzle I4 (see Figure 1) and falls upon the absorbent material or cotton in the cylinder IIJ. The nozzle I4 vis inserted into the nose and the bulb is pressed. The fumes from the medicine deposits enter the nasal passages and thus aiiord the user of their beneficial eiects. It is believed that this type of inhaler is superior to the one found on the market today and it is obvious that more eiectivev medication can be obtained by pressure rather than by the usual sniff-type inhaler. Also this type of inhaler can be used on infants where oil or other nasal sprays are not indicated for use by physicians. The mechanics of the general construction of the form is pressed a negative pressure results at the discharge end of the nozzle 29. The air from the trapping and accumulating chamber 2| passes up through the tubes 23 into the chamber 24 and then into the nozzle 29. The air currents discharging through the nozzle create suction and pick up and feed. medicated fumes issuing outwardly through the fume tube 21. A different mode of application of medicated fumes is thus acquired.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty suiiicient to clarify the construction of the invention vas hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

I claim:

1. In a hand pressuretype inhaler of the class described, a case transversely partitioned at one end to define separate chambers, one chamber for accumulation of air under pressure, an air furnishing bulb attached to one end of said case and communicating with said last-mentioned chamber, a plurality of communicating tubes mounted in said partition and aording communication at opposite open ends between said chambers, and a nozzle mounted on the opposite end of said case and substantially closing the end of the adjacent medicament chamber.

2. The structure specified in claim 1, in conjunction With a cylinder mounted in the medicament chamber and charged with absorbent cotton, and an elongated relatively small vapor pickup tube, said tube being embedded at one end in said absorbent cotton and having its opposite end projecting into and terminating short and inwardly of the discharge end of said nozzle.
